MINING AND QUARRYING MACHINE.

Application filed June 8, 1919, Serial No. 301,478. Renewed December 11,1922.

T all whom it may concern:

Be it known that I, CYRUS S. OLDROYD,

, a citizen of the United States, residing at Cincinnati, in the countyof Hamilton and State of Ohio, have invented a new and usefulImprovement in Mining and Quarrying I Machines, of which the followingis a specification, reference being had to the accompanying drawing.

My improvement relates particularly to machines used for cutting intoupright walls of coal, rock, or similar material, the -machinecomprising cutting means actuated by the machine and projected endwiseinto the wall of coal, or other material, and then moved sidewise tomake a sweeping out; the machine being, however, adapted to cut in avariety of other ways.

The object of my present improvement is to embody in such a machineeflicient means for propelling the machine.

By way of general statement, it may be said that the machine to whichthis invention relates consists of (1) a truck having a rigid frame orbody and having supporting or traction wheels adapted to rest onordinary rail tracks or on a floor; (2) a neck located. at the front ofthe truck body and rotatable on a horizontal axis extending lengthwiseof the machine and approximately in an upright plane cutting midwaybetween the track rails; (3) and cutting mechanism supported by saidneck and adapted to be adjusted for cutting in various directions. Theimprovement of this application relates only to the truck and to themechanism whereby power is transmitted from a motor supported by thetruck to the .truck supporting wheels, whereby the truck is propelled ineither direction at such relatively high-speed as is desirable formoving the machinewhenthe cutting mechanism is not in operation andalso-mechanism under the control of the operator for applying power fromthe truck motor to the truck carrying wheels for imparting such slowprogression to the truck as is desirable when the cutting mechanism iscutting.

For suchcutting mechanism as has been above. indicated, reference ishere made to my application for -Letters Patent of the United States,Serial Number-166,172, filed May 3, 1917, for an improvement in miningand quarrying machines. The machine of said application embodies a truckand propelling mechanism which differ in various particulars from thetruck and propelling mechanism of this application.

In the accompanying drawings,

Fig. 1 is an elevation of the right hand side of a machine embodying myimprovement, the cutting mechanism being shown the same as in my saidapplication Serial Number 166,172;

Fig. 2 is a plan of the same machine, a part of the cutting mechanismbeing omitted. and a part of the cover being broken awa Figs. 3 and 3together show an uprig it section on the middle longitudinal line ofFig. 2, Fig. 3 showing the rear part and Fig. 3 the forward part of themachine, the cutting mechanism being omitted;

Fig. 4 is an upright, transverse section on the line 1%, of Fig. 6,looking toward the left, parts i sing broken away;

Fig. 5 is a horizontal section on the line, 55, of Fig. 4; I r

F ig. 6 is a plan of the machine, drawn to a larger scale and some partsbeing omitted and others broken away;

Fig. 7 is an upright section onthe line, 7-7, of Figs. 4 and 6, lookingin the direc-' tion of the arrow, parts being broken away;

Fig. 8 is a plan of the mechanism shown by Fig. 7; i

Fig. 9 is a horizontal section on the line, 99, of Fig. 4:.

Referring to said drawings, A are four track wheels resting on trackrails, R. Said wheels are arranged in pairs on two horizontal axles, AEach of said axles rests in bearings, A, formed on the lower part of thebody, A, of the machine. Said body has-a floor or bed, A and a righthand upright .wall, A and a left hand upright wall, A

and a rear cross wall, A and a front cross wall, A.

Immediately at the rear of the rear cross wall, A, is an electricmotor,-M, having a shaft M from which power is to be trans mitted to theaxles, A 1

In the front cross wall A on the axial line of the motor, is a. bearing,D in which rests a neck, D, which supports the cutting mechanism. Saidbearing is formed by cutting out the upper edge of the cross wall, A andthe lower edge of a bearing block, D which rests upon the upper edge ofthe wall, A and between the side walls, A and A.v

The rear end of the neck projects through said bearing and istheresurrounded by a worm gear Wheel, D which bears against the rear face ofsaid cross wall. By this means the forward movement of said neck isprevented. Immediately at: the rear of the worm wheel is a frictionclutch member, D".

which has a sleeve, D extending forward into the neck. A neck shaft, D,lying within the neck extends rearward into the forward portion of saidsleeve and is keyed to the sleeve,"so that said clutch member and saidsleeve and said shaft must rotate in unison. At the rear of the neckshaft, the sleeve, D receives and forms a bearing for the forward end ofthe main transmission shaft, B, which is joined to the motor shaft, M bymeans of a coupling,M p

The function of the neck shaft is to transmit power to the cuttingmechanism as described in my said application Serial Number 166,172.Rotation is imparted to the worm wheel, D, and the neck, D, by themechanism described in my above-mentioned ap lication.

n the main. transmission shaft, B, is a i s iral ear wheel Bwhich-meshes with a spiral gear wheel, B which is loose on the uprightshaft, B, which rests in bearings, B and B. On the bearing, B reststhelower end of a spacing sleeve, B, which surrounds the shaft, B, andsupports a bevel gear wheel, B which. is cast integral with the spiralgear wheel, B The bevel gear wheel, B meshes with the bevel gear wheel,

B which is fixed on a shaft, B", resting in a bearing, B and extendingthrough the side wall, A On the outer end of said shaft is fixed acrank, B towhich is coupled the lower end of a pitman, B The upper endof said pitman is coupled to a rocking member, B, which is hinged on thehorizontal shaft, B. On said shaft is fixed a ratchet wheel, B and onthe rocking member is a reversible pawl, B which engages the teeth ofthe ratchet wheel. A slide member, B is pressed by a spring, Bl", towardthe pawl and thus controls the pawl. B, is a gear worm, B, which mesheswith a worm wheel, B, which loosely surrounds the shaft, B, below thebearin B From the spiral gear wheel, the spiral gear wheel, B receivesconstant rotation, and through the bevel gear wheels B and B and theshaft, B, and the crank, B and the pitman, B and the ratchet wheel, Band a shaft, B and the Worm, B", the worm wheel, B, receive constantrotation.

But since the wheel, B, and the wheel, B are loose on the shaft, B, saidshaft does not receive rotation for either of said able endwise on saidshaft and so as to com- On the shaft,

pel the rotation of said shaft when the clutch is rotated.

In the upper face of the spiral gear wheel, B are sockets, B adapted toreceive the lower jaws of the clutch. *on the lower side of the wormwheel, B is a jaw clutch member, B, which is adapted to be engaged bythe upper end of the clutch, B.

At the middle of the clutch,'B ,is a circumferential groove, B in whichrests a clutch ring, B on which are diametrically Each of'saidoppositely located studs, B 3. 7 studs is engaged by a horizontal fork,B, which is rigid on a rock-shaft, B, which is transverse to the lengthof the machine and associated with a quadrant, B", which has threenotches, B. I

Rocking the shaft-,B, causes the raising and lowering of the clutch, BShifting the quadrant lever causes the rocking of the rock-shaft throughthe. actionfof the con necting rod, B and the arm, B -'The parts are soproportioned as that when the quadrant lever is set on the middle notch,B, the clutch, B is heldv in neutral positionout of engagement with boththe wheel, B and the wheel, B -'and that 1 when the quadrant lever isset on oneof the other notches,the clutch is in engagementwith eitherthe wheel, B or the wheel, B. I

When-the clutch is in. engagementwith the wheel, B the transmission isdirectly from the main shaft, B, through the whee B and the clutch tothe shaft, B, \Vhen the clutch is in engagement with the wheel, B, thetransmission is through the lower course, including the crank, pitman,and ratchet mechanism and the wheel, B On this course there isreductionof velocity by the ratchet mechanism and also from the shaft, B, by theworm, B", to the worm wheel, B. This transmission is reversed byreversing the; pawl, B

This reducedvelocity is to be utilized when the machine is cutting. Thehigher velocity received through the direct transmission is to be usedwhen themachine is to be moved while it is not cutting. Whenthatvelocity is used, the direction of travel of the machine is to bereversed by reversing the motor, M. But during the cutting operation themotor must not be reversed. Hence, the mechanism which provides the slowor cutting propulsion of the machine is made reversible.

On the lower end of the u ii ht shaft, is fixed a bevel gear wheel: fiwhich meshes with a bevel gear wheel, A on the rear axle, A Thewheel, Ameshes with and meshes with a bevellgear wheel, A,

on the front axle, A When the shaft, 13,

is rotated, there is transmission of motion from the bevel wheel, B tothe bevel gear wheel, A and from the latterto the ad a cent axle, A andfrom the bevel gear, A

to the bevel gear wheel, A. From the latter there is transmissionofmotion through the shaft, A and the bevel gear wheels, A and A to thefront axle, A Through the gearing intervening between the two axles, Asaid axles are held for movement in unison. I

Going from the axle, A toward the motor, M, the shaft,- B may beregarded as the first shaft while the shaft, B, is regarded as thesecond shaft. And the transmission shaft, B? and B, may be regarded,respectively, as the third and fourth shafts. I

The mechanism for controlling and varying and reversing the transmissionfor propulsion is all located above the wheel axles at a convenientelevation within the body of the machine where there is ample space forsaid mechanism and'the mechanism is accessible and protected. On therear axle 1s fixed a brake drum,

A A brake strap, A is applied around said drum. One end of said strap isap plied to the front face of the cross wall, A

Thence said strap extends downward beneath the drum, A and forward andupward above the drum. To that end is coupled the front end of ahorizontal connecting rod, A Said rod extends rearward through anaperture, a, in the strap, A and thence rearward to a quadrant lever,

1V which is combined with a quadrant,

A to permit under strain.
